SPECIFICATION forming part of Letters Patent No. 631,630, dated August22, 1899.

Application filed November 19, 1898. Serial No. 696,871. (No model.)

To all whom it may concern@ f Be it known that we, J AMES GARRETT andJAMES WELCH, both of Monaca, in the county of Beaver and State ofPennsylvania, have invented a new and Improved'Brick-Machine, of whichthe following is a full, clear, and exact description.

The object of the invention is toprovide a new and improvedbrick-machine more especially designed for working soft clay andarranged automatically to -cut off and remove the surplus material fromthe top of the molds during the passage of the latter from the machine.

- The invention consists of novel features and parts and combinations ofthe same, as will be fully described hereinafter and then pointed out inthe claims.

Reference is to be had to the accompanying drawings, forminga partofthis specification, in which similar characters of reference indicatecorresponding parts in all the views.

Figure 1 is a perspective View of a brickmachine having the improvementsapplied. Fig. 2 is a perspective view of the improvements detached fromthe machine, and Fig. 3 is an enlarged transverse section of the tableon the line 3 3 in Fig. 2.

The upright brick-machine (illustrated in Fig. 1) is provided with theusual framework A, in which reciprocates a plungerB, connected by apitman C with a rcrank-arm D, rotated in the usual manner to impart areciproca ting motion to the plunger B and press the material into themolds E', arranged on the under side of the framework A. The means forfilling the molds with material and for'pressing the material in placemay be of any approved construction, and hence further description ofthe same is not deemed necessary.

On the discharge side-that is, on the front of the machine and directlyover the discharged mold'sE-is arranged a table F, hung at F' on arod'G, carried by brackets G', attached to the sides of the mold-carrierE. The table F is reinforced at its sides by transversely-extending ribsF2, projecting beyond the inner or free end of said table F to beattached to a tie-rod F3, held on springs II,'sus pended from bracketsH', likewise secured to the mold-carrier E. The ribs F2 extend on theouter side of the table beyond the ends of the molds, so as not to comein contact with the material contained in the molds, and on the top ofthe table F, at the free end thereof, are arranged similar ribs F4, alsoleading to the tie-rod F3, said ribs being spaced according to thepartitions in the molds, so as not to come in contact with the materialcontained in the molds. The free end of the table F is bent downward andoutward, as is plainly shown in Fig. 2, and a receiving-plate F5 isriveted to the end of the table, and somewhat in front of the edge ofsaid plate F5 is arranged a cut-off device I in the form of a Wire heldin the ribs F2 of the table, one end of the Wire being drawn on by aspring I', which serves to hold the wire tight across the table and topermitthe wire to yield when striking an obstruction.

From the foregoing it is evident that the table Fis mounted to swing upor down on the rod G, and its free end is spring-supported, so as topermit the table to yield upward. when the filled molds are pushed outof the machine, and the rod forming the cut-oif device I strikes off thesurplus material from the molds and causes the said material to pass upthe plate F5and upon the table F. Thus when the filled molds are pushedout of the machine by the action of the empty molds in vthe brick-pressthen the cut-offV device I removes the surplus material from the moldsand delivers this material upon the table F, extending over the lledmolds.

In order to remove the surplus material from the table, we provide asweep J in the shapeof a plate set vertically on one end of the table Fand adapted to travel over the same, together with a pipe K, attached tothe v -sweep and connected by a Iiexible hose K' with a water or otherliquid` supply for supplying the table F lwith, water'to insure a properremoval of the material when the sweep J moves over the table from oneend thereof to the other. The sweep J .is provided With a bearing J',engaging a guiderod J2, secured in the brackets G"directly above the rodG, so that the said-sweep J reciprocates over the table Fin thedirection of said rods G and Jz.- Buffer-springs .J3 are coiled on theguide-rodJ2 next the brackets G', so as to ease the movement of thesweep IOO on nearing the end strokes. The sweep J is pivotally connectedat its back by a link J1 with an arm L, secured to or formed on ashaft'L, journaled in suitable bearings on the upper end of theframework A, said shaft also having an arm L2 in the path of andactuated by the crankarm D, connected with the pitman C, as previouslyexplained. On the arm L is arranged a weighted arm L3 for insuring arapid return movement of the sweep J after the said sweep has beenpushed over the table in the direction of the arrow a' to remove thesurplus material and push the same over a chute N into an elevator O ofany approved construction for conveying the material to a suitable placeof discharge. It is evident that after the molds are filled in themachine and the pitman C rises to its first position then the crank-armD imparts a swinging motion to the arm L2 to turn the shaft L', so as tocause the arm L to move the sweep J forward in the direction of thearrow a' for removing the su rplus material of the last-filled mold fromthe table F. \Vhen the pitman C is on its downward movement to cause theplunger to ll the next mold with clay, then the crank-arm D releases thearm L2, and the weighted arm L3 now causes a return movement of the armsL and L2 to draw the sweep J back to its previous position, asillustrated in Figs. l and 2. As the iilled molds move out of themachine the cut-oit device l removes the surplus material, as previouslydescribed, and as this material passes upon thc table F it is removedtherefrom by the next movement of the sweep J, as previously explained.

The free end of the table F is curved downward and forward, so as topress firmly upon the top of the mold and cause the wire I to remove allthe surplus material from the mold and cause said material to pass uponthe table F.

Having thus fully described our invention, we claim as new and desire tosecure by Letters Patentl.
